TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 397,845, dated February12, 1889.

Application filed June 6, 1888. Serial No. 276,197. (No model.)

To @ZZ whom z' may concern:

Be it known that I, ALFRED G. FISHER, a citizen of the United States,residing at Springfield, in the county of Hampden and State ofMassachusetts, have invented new and useful improvements in TemporaryBinders, of which the following is a specification.

This invention relates to temporary binders particularly adapted for theretention of sheets of music, although perfectly adapted for use forconfining other kinds of papers and pamphlets; and the inventionconsistsA in the combination, with the back or folding portion betweenthe two covers, of two or more transversely arranged arch shaped hooks,which, by their inner ends, are secured to said back, and by their outerends terminate in extensions parallel with the inner surface of saidback at a short distance therefrom and each extending` toward the saineend of said back, substantially as will hereinafter more fully appear;and the invention further consists in the embodiment of other featuresof novelty in the formation of said hooks, all as will be particularlyshown, described, and pointed out in the claims.

Reference is to be had to the accompanying sheet of drawings, in whichthe present invention is illustrated, and in which-A Figure 1 is aperspective view of t-he inclosing-covers shown as opened with theretaininghooks applied in place on the inside of the back or foldingportion thereof, and showing 1 end extended through the thickness of thein dotted lines the position of a single sheet as interlocked with saidhooks.

the confining-hooks thereon, and the adjacent portions of the covers,there being indicated in dotted lines the relative position of a sheet aview illustrative of a modiiied form of hook. In the drawings, A Arepresent the side covers, of board or other sufficiently stiff ma- Fig.2 is a per- I spective view, enlarged, of said folding back, i

terial, intermediately joined by any suitable iiexible connection withthe back B, as ordinary in book-covers. On the inner side of the backand toward the ends thereof are archshaped metallic hooks a a, standingtrans versely of its length, which, by their one end portions, 6, areconfined on or against said back, and their other end portions areangularly projected in the extensions S 8 longitudi nally of and towardone and the same end of said back and in a line slightly within' andseparated from the inner face thereof.

It is preferable to form the longitudinal extension S of one hook longerthan the corresponding extension of t-he other hook, and it is alsopreferable to form both of said hooks integrally with an intermediateshank-wire, .10, as seen in the drawings, Figs; l, 2, and 3, saidintermediate shank-wire being at suitable portions of its lengthflattened, as at 12, th rough which perforations are formed to permit ofthe riveting of said wire to the back, and thereby secure the same andthe rigid and integrally-formed hooks in their proper positions relativeto said back and to each other. Other means for securing said shank-`wire to the back than riveting might be employed, as stitching orlooping; and, again, the hooks need not necessarily be joined by theintermediate wire, l0, for, as seen in Fig. 5, they may be eachseparately formed and have the end portion, 6, thereof shouldered, as atl5, just within its extremity and said back and riveted at the outerside thereof.

The music or other sheet or sheets d are to be near their inner edgesprovided with perforations, as indicated at 18 in Figs. l, 2, and 3,which perforations are spaced at a distance from each other equal to thedistance between the hooks a a; and to place one or more sheetsperforated, as described, for confinement on said hooks, said sheet orsheets are slipped by their inner edge under the longitudinal eX-'tensions S of the hooks, with their perforations 18 near the points ofthe'said extensions (and where one of said extensions is longer than theother when one perforation will be coincident with the point of thelonger extension the other perforation will be at a slight distancebeyond the point of the shorter exten- IOO the junctions otf saidextensions S and thel arched portions ol' the hooks, and the sheet maythen be swung` over on said arched hooks 3 into the relation therewithand position indi cated in Figs. ll and -l-, and oi course l'ollowr inga reversal ot' the movements ol.' the said steps will efl'eet adetachment ofthe sheets l lrom the binder-hooks.

The formation ot one hook-cxtension S longer than the other isadvantagmms, lorthe r reason that in securing an engagement thereot'with the pertorations of the sheets, as partieularly noticeable in lfig.il, it is only necessary to exercise care to secnrea coincidence of oneperforation with the longer extension, and when a partial engagementtherebetween has been securedthe other perforation may Abe easilybrought to and about the other and shorter extension; but the .inventionis not to be limited to t-he formation of said extensions S of varyinglengths, as when .formed of equal lengths the devices are equallyeffective, but not as convenient in use. In the use of the presentbinder the sheets may lie as perfectly flat at their inner edges as atany other portion thereof, an d the susce} 'itibility of the binder'l'or such desirable disposition ot the said sheets coi'ii'ers upon itan important advantage. More than two hooks substantially such asdescribed might be employed in some instances where sheets or folios ofconsiderable height are to be held between the covers,

and in such an event perforations are to be made near the edges of suchsheets in number and of interval corresponding with the number andinterval of the said hooks. lhat I claim as my invention is l. 4Thecombination7 with the back B, of two or lmore transversely-arran gedarch-shaped hooks, a, which by their one end portions are l rigidlyconfined upon said back, and at their f other end portions are providedwith the an gular projections S, extending at a slight distance from andparallel with the inner sur- .tace ot' said back in the direction ot'thelengtfh and with their points towawlv one and the i saine endthereol,substantially as and 'orthe purpose described.

il. The combination, with the back l, ol two transversely-arrangedareh-shal'ied hooks, fl d, l which by their one end portions are rigidlyconfined upon said bat-k, and at their other end portions are providedwith the angular project ions S, one olf which is longer than the other,exteluling ata slight distance trom and parallel with the inner suri'aeeot' said back in the direction of the length and with their pointstoward one and the saine end thereof", substantially as and ior thepurpose described.

3. The hoolc device t'or temporary binders herein described, the samebeing integrally formed andv consisting ol the intermediate shank-wire,lt), the arclrhooks uy d at the end portions oi said shank-wire, eachextended in planes at right angles thereto, and each at its end providedwith a projection, S, extending parallel with said shank and from ortoward one and the saine end thereof, substantially as described.

4L. The hook device herein described, the same being integrally t'orniedand coiilsisting of the intermediate shank-wire, 10, having theiiattened andperforated portions 12, the arch-hooks d cl. at the endportions ot.' said shank-wire, each extended in planes at right anglesthereto, and each at its end provided with a projection, S, eachextending parallel with said shank and t'rom o'r toward one and the sameend thereof, combined with and rivl eted to the back B, allsubstantially as shown .and descrbral, i'or the purpose speoiiied.
